I just can't make any of my usb sticks work with R30 I own... I've got one older stick (Kingston Data Traveller 2 512Mb), but no universal drivers seem to work with it, or actually with any of my sticks. Tried a gazilion of different options.

That's what I use on my 380XD with 98SE. I have a 1GB stick I use just for that computer. I installed the software, restarted, plugged in the stick and selected the driver. Slow as molasses (because that computer is USB 1.0, after all) but it's easier than burning CDs or hunting down my parallel ZIP drive in a closet someplace.
